Description

A kind of ring suspender of mechanical control

Technical field

The present invention relates to large-sized forging ring lifting device, specifically a kind of ring suspender of mechanical control.

Background technology

In the manufacturing process of large-sized forging ring, hot ring handling is very arduous work.Because ring weight is heavier, so hoist tool is relatively heavier; And ring red heat state often makes the workman in operating process, promptly pay heavy muscle power to bear 1000 ° of hi-heat bakings in the left and right sides again that operating mode is very abominable.Designing a suspender that relies on mechanical system control operation process fully, realize the hommization production process, is to forge the long-cherished wish that ring handling workman dreams of.The present invention is exactly suspender that relies on mechanical system control operation process fully so.

Summary of the invention

In order to address the above problem, the present invention provides a kind of ring suspender of mechanical control easy to use.

For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:

A kind of ring suspender of mechanical control comprises hanger beam, strut bar, hold-down arm, suspension hook and supporting plate more than 3 or 3;

Crossbeam is suspended on the carrier below through slide fastener and/or extension spring, and crossbeam one end is hung with hold-down arm, and the bottom-hinged of hold-down arm has suspension hook; The outer wall Joint of the other end of crossbeam and slide bar, slide bar are hollow tubular structures, and slide bar and crossbeam are perpendicular, and the center of slide bar equates to the distance of the suspension strut arm end of each crossbeam;

Boring at slide bar is coated with the pull bar that connects slide bar, and the pull bar lower end is fixed on the supporting plate; At slide bar outer wall upper sleeve through sliding sleeve is arranged, the sliding sleeve lower end is fixed on the supporting plate, and is hinged through strut bar between sliding sleeve and the hold-down arm.

Be hinged between crossbeam and hold-down arm; Captive joint with supporting plate in the pull bar lower end; Hold-down arm rectangular distribution around the center fixation frame, crossbeam and arm quantity are complementary; The two ends of strut bar are hinged respectively and between the outer wall of sliding sleeve and hold-down arm; Sliding over the slide bar outside face and slide up and down, captives joint with pull bar through supporting plate in the bottom; Pull bar upper end is hinged with pair and colludes the extension spring drag-line, and pair is colluded extension spring drag-line upper end and is hinged with pair and colludes; The suspension ring below is hung with carrier, and carrier links to each other with crossbeam through carrying slide fastener and/or suspender extension spring.

Ring suspender of the present invention is very convenient to use, particularly is in when using under the abominable situation of operating mode in ring, can operate away from ring, has improved the working environment of workers, relies on mechanical system control operation process fully.

The specific embodiment

As shown in Figure 2, a kind of ring suspender of mechanical control comprises the crossbeam of (is 3 at this) more than 3, arm, strut bar, suspension hook, suspender extension spring; Suspension ring, carrier carries slide fastener; A pair is colluded the extension spring drag-line.

Suspension ring 1 are fixed on carrier 2 tops; The carrier 2 that carries slide fastener 3 and suspender extension spring 4 and their tops is articulated and connected, and is articulated and connected with the hanger beam 6 of their belows; Hold-down arm 7 is articulated and connected in the hanger beam below, and hold-down arm 7 is articulated and connected with suspension hook 12, is articulated and connected with strut bar 8; Strut bar 8 is articulated and connected with sliding sleeve 9; Sliding sleeve 9 is captiveed joint with pull bar, with slide bar 10 sliding block joints; Slide bar 10 is captiveed joint with hanger beam 6, with pull bar 11 sliding block joints; Pull bar 11 colludes extension spring drag-line 5 with pair and is articulated and connected.It all is metal construction.

Specifically can be described as:

Crossbeam 6 is suspended on carrier 2 belows through slide fastener 3 and extension spring 4, and beam-end is hung with hold-down arm 7, and the bottom-hinged of hold-down arm 7 has suspension hook 12; The outer wall Joint of the other end of crossbeam 6 and slide bar 10, slide bar 10 are hollow tubular structures, and slide bar 10 is perpendicular with crossbeam, and the center of slide bar 10 equates to the distance of the suspension strut arm end of each crossbeam 6;

Boring at slide bar 10 is coated with the pull bar 11 that connects slide bar 10, and pull bar 11 lower ends are fixed on the supporting plate; At slide bar 10 outer wall upper sleeve throughs sliding sleeve 9 is arranged, sliding sleeve 9 lower ends are fixed on the supporting plate, and are hinged through strut bar 8 between sliding sleeve 9 and the hold-down arm 7;

Suspension ring 1 below fixed suspension has carrier 2, and carrier 2 links to each other with crossbeam 6 through carrying slide fastener 3 and/or suspender extension spring 4; Pull bar 11 upper ends are hinged with pair and collude extension spring drag-line 5, and pair is colluded extension spring drag-line 5 upper ends and is hinged with pair and colludes;

The quantity of hold-down arm 7 is more than 3 or 3, its rectangular distribution around the center fixation frame, and crossbeam and arm quantity are complementary.

Principle of work, as shown in Figure 1;

A master is hooked on the suspension ring 1 and carries suspender, and pair is ganged up with pair and colluded 5 retinues of extension spring drag-line.To ring, vertically fall.

The master colluded and stops descendingly when the B suspension hook placed the ring bottom position, and pair is colluded and is pulled upwardly extension spring drag-line 5 and sliding sleeve 9, and suspender hold-down arm 7 is launched; The master colluded pair and colludes simultaneously and move down when drop hanger 12 supported the ring inwall, and when suspension hook arrived at the ring bottom, main colluding stopped; Pair is colluded and is pulled upwardly; This moment, pair was colluded 5 loads of extension spring drag-line, the elongation of extension spring drag-line, and suspension hook firmly hooks the ring bottom.

C master colludes and is pulled upwardly, and elongation is carried in suspender extension spring this moment 4, and pair is colluded extension spring drag-line 5 and shortened, and carries slide fastener 3 to suspender ring is sling, and leaves former station.

When laying station, the main pair of colluding is colluded simultaneously and is fallen with the ring handling for D driving.

When E arrived at bearing surface when ring, the main pair of colluding was colluded and is continued descendingly, and the suspension hook arm begins to shrink, and suspension hook breaks away from the ring bottom, and this moment is main colludes pair to collude beginning up, suspender is left shift out ring, carries out handling next time.

Annotate: arm is (is 3 at this) more than three or three at least.Extension spring on the suspender is identical with arm quantity, the making a concerted effort less than the ring total weight and greater than suspender weight of pulling force.The weight of hanger beam is greater than the total weight of hold-down arm.Pair is colluded the pulling force of carrying extension spring greater than the weight of arm total weight less than hanger beam.
